In real estate law, real estate refers to land and all things permanently affixed to it. This includes buildings, fences, trees, and other improvements, as well as items attached to structures, such as heating systems, plumbing fixtures, light fixtures, and similar components.
Real estate is distinguished from personal property, which consists of movable items not permanently attached to the land or structures. The classification of property as real estate determines how it is transferred, taxed, and regulated.
